My 07 JK is running really rough at low rpm, and the oil has a strong smell of gas, I've changed the oil and spark plugs #2 was really dirty and oily. Any suggestions on the issue? I'm hoping its not a piston ring

If your injectors are malfunctioning they could be wetting the cyls. Excess fuel can solvent wash the cylinders and take out the rings! Have it checked by someone who is good with fuel side work - and do a compression check.
